Reviewed by Chris Dumez.
I pre-merged a little code from https://github.com/WebKit/WebKit/pull/39148 so
we don't end up conflicting.
* Source/WTF/wtf/IndexedRange.h:
(WTF::BoundsCheckedIterator::begin):
(WTF::BoundsCheckedIterator::end):
(WTF::BoundsCheckedIterator::BoundsCheckedIterator):
(WTF::boundsCheckedBegin):
(WTF::boundsCheckedEnd): use std::begin / std::end so we can do indexed and
zipped ranged for loops on C arrays.
* Source/WTF/wtf/TrailingArray.h: Paragraph separate first from last. (I came
here to try to add data(), but it's there already.)
* Source/WebCore/html/canvas/WebGLRenderingContextBase.cpp:
(WebCore::WebGLRenderingContextBase::texImageImpl): Updated for span.
* Source/WebCore/platform/graphics/GraphicsContextGLImageExtractor.h:
(WebCore::GraphicsContextGLImageExtractor::imagePixelData): Use span and
MallocSpan because UniqueArray doesn't know its length.
* Source/WebCore/platform/graphics/cg/GraphicsContextCG.cpp:
(WebCore::GraphicsContextCG::setCGStyle): Use zippedRange instead of raw
indexing into a C array.
* Source/WebCore/platform/graphics/cg/GraphicsContextGLCG.cpp:
(WebCore::getSourceDataFormat): Use std::array and std::span.
(WebCore::GraphicsContextGLImageExtractor::extractImage):
* Source/WebCore/platform/graphics/cv/GraphicsContextGLCVCocoa.mm: Use
std::array.
